How can my process of modeling be Sped Up?
There is no magic bullet. The only real way to get faster, is to practice and learn about the different tools available to you (watch tutorials).

As you practice, you start to notice things that you do a lot, and eventually you might find a tool that can achieve a task faster. Tutorials help speed up the process, but they only show what the tools can do, not how you should use them. 

You also might find that you work faster with a certain tool than other people. Essentially, some people work well one way (and that's what they'll teach), and others work better other ways. 

Lot's of things can be taught in tutorials, but you can only learn to do those tasks quickly as you become comfortable with them. The only way to become comfortable with them is experience.
